To all wil/ont it Netty concern:

Be i t known that LRUDoLrH SonnNoii, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented certain new and useful improvements in Valves for Gas-Generators, oi' which the following is a speciiication.

This valve is adapted and intended more particuiarly for use in apparatus for the manufacture of water-gas, but it can be used in other places in wh ich itis desirable to employ a valve that will be capable of withstanding a high degree ot' heat and pressure and which at the same time will provide a tight seal to prevent the escape oi gases.

Another object of the invention is to provide means for regulating the valve to allow for expansion and contraction of the parts from heat or other causes and to enable the parts to he initially regulated to 'form aciose tight seal.

A AFurther object ot' the invention is to provide means for cleaning out ashes or products of combustion from the interior oi' the valvecasing and also to provide means for obtaining access to the operative parts of the valve, and a linal object oi' the invention is to improve the construction and operation of the valve as a whole, making it strong and durable and at the same time easil)T adjustable to meet the requirements of use.

'I The invention consistsin the features ot' construction and combination of parts -hcreinafter described and claimed.

in the drawings illustrating the invention, Figure l is a plan view, partly broken away, showing the valve-door seated; Fig. 2, a sectional plan View ofthe valve and casing, showing the door unseated; iFigziB, a sectional elevation taken on line 3 3 ot' Fig. l lookingin the direction of the arrow; Fig. 4i, a modiiication of the cap of the valve-casing; Fig. 5, a sectional elevation taken on line 5 of Fig. l looking in the direction ol" the arrow, with the cap or covering of the casing removed; Fig. 6, an enlarged detail, partly in section, o'l the arm and door, showing the mounting' for the same; Fig. 7, an edge elevation of the casino' showing' the door and stuliing-box;

and Fig. 8, a detail in section of the stuhing- L box and operating' parts.

rEhe valve is constructed to have a shell or casing 1, preferably of cast metal, closed bjr moans oi' a seinicircular cap 2, each of the sections being provided with fianges 3, secured together by bolts i or other similar means. The boda/'section l is provided with flat side walls 5 and edge walls 6 and 7' ol suitable configuration to allow room vfor operation et the valve-door, and between the edge walls is an opening 8, closed by means of a door-plate 9, having' therein a ianged opening 10 for the seating of a door ll. The door-plate is provided on one side of the llang'ed opening with outwardly projecting ears l2, spaced a considerable distance apart, and between the ears and in facial contact therewith are a pair ot hinges 13, cast onto and outwardlj,7 projecting :from the door 11, and between the hinges and in line therewith is an t-shaped locliing arm 14.-, and the locking-arm and door-hinges are pi voted by means ot' a single pin or bolt l5, which passes through the ears, the hinges, and the looking-bar, as shown in Figs. l, 2, and T. The door is provided in its center with a recessed boss 16 and the locking-arm is provided in its center with an enlargement l?, through which passes a screw threaded stud 18, the end of which is adapted to enter the recessed boss in the door, and the screwthreaded stud terminates in a cross-arm i9 for enabling the stud to be turned to exert pressure against the door.

@n the side ol the door opposite that on which are located the ears 12 are a pair of ears Q0, between which is located a strap 2l, consisting of side arms 22 and a cross-head 23, and thestrap is pivoted between the ears by means of' pin or holt 24, which allows the strapas a whole to be swung down over the end ol the L-shaped locking-bar when thrown into position to close the door, so that the locking-bar will be held against outward projection as the screw-threaded stud is turned,

therebyv exertinga continuous pressure against the door for lorcing it into place.

valves ofv this class the parts are often subjected to a very high degree of heat, which causes expansion and contraction and is liable to cause a. certain amount of warping' or bulging of the parts, so that if the door were fastened rigidly to the arm it might be impossible to perfectly seat the door under all circumstances. By connecting' the parts in the manner indicated the door will iind its proper seat and adjust itself to existing' conditions. By beveling or sloping the seating-face of the door and the seat therefor it will be impossible to swing the door beyond a predetermined point, for the reason that when the door has reached its proper position it will be wedg'ed into place and further movement will be impossible. By this wedging action the door is prevented from beingswung beyond the opening which it is intended to close, and at the same time makes the tightness of the seal dependent upon the degree of revolution of the operating-shaft. It will often be necessary to adjust the door somewhat after it is properly positioned by reason of the fact that an initial adjustment must be made and subsequent adjustments made in case the parts become warped or bulged by excessive heat. Such adjustment can be readily made by projecting or reti-acting the diagonally-disposed adjusting' screws or studs which bear against the adjusting-plug 43, against which the squared body of the operating-arm abu ts. At the same time the operating-shaft and the adjustingnuts are so packed that it will be impossible for gas or vapor to escape, which of course is a mattei' of great importance in the art to which the present invention relates. By forming the refractory lining for the lues of Sullicient thickness to have its edge overlap the metallic portions of the casing the latter will be preserved from the direct action of the heat, which otherwise would tend in a short time to fuse or impair the parts. The method provided for cleaning the interior of the casing enables ashes or sediment to be readily removed, which would otherwise collect within the casing and prevent the valve-door from being swung' back suiiiciently to entirely clear the valve-opening, which it is necessary to do in order that no portion of the door may project into the line of travel of the products of combustion. If no means were provided for cleaning the casing at this point,lthe collection of ashes and sediment would in a short time be sufficient to prevent the door from being turned completely back into position, thereby allowing its projecting edge to lie directly in the dr ft through the fines, which would quickly fuse or burn olf that portion of the door. By providing a cap for the casing of the form shown it is possible to cast the entire casing in but two parts, which can be quickly secured together and firmly united. It will be seen from the foregoing description that the valve as a whole is simple in construction and operation and that the parts are so arranged that they can be readily adjusted and properly positioned.
